RIOX2
Chr 3ribosomal oxygenase 2
Also known as: JMJD10, MDIG, MINA, MINA53, NO52, ROX
RIOX2 encodes an oxygenase that demethylates histone H3K9me3 to increase ribosomal RNA expression and hydroxylates ribosomal protein L27a, playing a key role in ribosome biogenesis and cell growth. Mutations cause autosomal recessive intellectual developmental disorder with short stature and variable brain malformations. The gene shows very high constraint against loss-of-function variants, indicating that complete loss of function is likely incompatible with normal development.
